always the latest firmware. I read dpreview every week and update firmware immediately whenever they get released. Well, since the mapping worked I will leave it at that. I'm just grateful you guys were able to help me so quickly! :D

Yeah I've had mine for almost a year and there's maybe 15 or so of these things that I've counted (so far). I just tried the 'Pixel Mapping' feature you spoke of and it seems to have worked. Thanks much. If I go to get it serviced can they actually fix the dead pixels?

I've got a Pentax K7 which I've been using for months but I just noticed these image artifacts when I super zoom into photos. They seem to be crosses and circles. Usually blue but also green, yellow, and red.

What the heck happened? Do I need a cleaning? repair? or is it a problem with the camera?

I'm attaching samples from 3 separate images taken indoors and outdoors.

When i jiggle my K7 or turn it upside down I can feel a slight clunk movement inside.

It's works great (just got it today) but is it supposed to feel completely solid when you jiggle/flip it or is there supposed to be some movement inside?

:P Not many of us have more than a few lenses anyhow. Options are limited and if a camera told me I needed a better lens I'd have to beat the crap out of it and demand it give me the $600 I need for a new one, lol.

K20D's days are numbered???

No one here mentioned the obvious.

The main difference is the K7 takes video since their ability to take good shots should be very close in the right hands.

The question to be answered: "Is taking video worth paying [$1300 for the new K7] vs. [$600-700 for a K20d]"

How many people can shell out an extra $700 for video and some extra features? Is it worth it?

Err. My bad. I thought it was DA*. I was reading what the designation meant last week.

Pentax posts - PMA 2008 - CNET Blogs


AL = Aspherical Lens
DA = designed for digital (not full frame) cameras
DA* = DA with dust- and weather-sealing
ED = Extra low Dispersion
IF = Internal Focus
SDM = Supersonic Drive Motor

I would think that the Pentax 18-250 automatically beats the Tamron because it's just a rebranded version with the addition of "DA series" meaning the Pentax has full weather sealing.

Question: Why wasn't Sigma included in the Poll? Do they suck or something?

GREAT Beginner DSLR owner tips
Posted By kiamon

Here are the full 12 tips from the first page and why it helped me.

I don't want to steal credit from the site for posting their stuff so I'll post their URL again (digital slr guide online photography course) and give props for a bunch of good info. They have photography blogs on other info too.

1. Don't throw your camera manual away. It will become your new best friend. Read it as often as possible, especially in the first couple of months after purchasing your DSLR camera. Always store it somewhere handy. For example in your camera bag.
- My manual is in CHINESE :(. I downloaded the nglish one from the Pentax website though so it's not a total loss.

2. Buy a UV filter for each lens you own. It's easier to replace a scratched lens filter than it is to replace your actual lens.
- I actually asked this in a previous post. Since I'm a beginner I don't know what flare is yet. My only worry is damage and having to spend more $.

3. Learn to use all your SLR camera settings. Even those you don't think you'd ever use. Practise changing settings like ISO, aperture and shutter speed, so you know them like the back of your hand. A moving animal won't sit and pose until you work out your settings.
- Yes this is good advice but also the most time consuming. Also more difficult initially when I don't know what the hell these things do.

4. In addition to UV filters, other important pieces of equipment should include a sturdy tripod and a remote release. They both come in handy for taking photographs that require long shutter speeds. For example night photography or slow motion water.
- I learned this from camera shake. I am on the first stage now of learning how to steady my own hands (I'm not buying a tripod until I get this part right). Tricks like stop breathing, brace your elbows on your chest or another object. Place your camera on an object as a brace like a handrail or wall or pole. Or wrap the strap around your neck and extend the camera until the string is taut.

5. You can never have enough SLR / DSLR photography magazines and books to learn from. The best ones will explain what camera settings were used, along with each photograph displayed.
- I did the magazine and look at photos thing but I have come to realize that they aren't worth much (actually diddly-squat) unless the camera and settings are posted too. Cause without the settings/equipment then I won't know how the hell they got such a great shot.

6. Don't touch or blow on the mirror inside your camera body when you have the lens off. If you damage the sensor, you may as well buy another camera body, because that's how much it will cost to fix. If you notice spots appearing in your photos, buy a cleaning kit or dust blower from your local camera store. Many now have an inhouse cleaning service which is always a good alternative.
- I think the concern here is for clumsy people. Not everyone is dextrous and some amateur may mistake 1 part for another or bump around in there and scratch something. Better to be safe unless you are familiar.

7. Don't change your lens outside if it's windy. Put the main lens on your camera before you leave the house. If you need to change the lens outside, face the camera body downwards. Dust can't fall upward onto the camera's sensor.
- This is good advice. I am going to e using primes and I worry about possible dust getting in.

8. If at first you find your getting a lot of blurred photo's, change to a fast shutter speed. The faster the photograph is taken, the less chance there is of it being effected by camera shake. Holding the camera closer to your body or resting it on a nearby object is also a good tip. If you're taking nature shots, steady yourself by leaning against a tree.
- Yeah, I'm still trying to get the hang of this. The balancing between shutter and light. I am using a flash now to save me the trouble :D , now if only I can learn how to use the flash properly... lol.

9. When you buy a digital camera bag, think about the future. Many photographers on average own at least 3 lenses. Personally I own 2 camera bags. One holds a camera with a single lens. This is useful for times when I know I'll only be needing one lens. For example, if I'm going out to photograph landscapes I don't need to lug myself down with all 3 lenses. Or if I'm going out to photograph macro's, then I don't need to also carry my landscape lens. My second bag carries my camera and all three lenses. This one is useful for travelling purposes.

10. Learn what RAW file format is. Setting your digital camera to shoot in RAW is particularly useful for beginners to SLR photography. If you have your camera's white balance or picture style set wrong when you take a photograph, you can change this later on with a RAW editor on your computer. There will also be many times when you only get one chance to take the photograph. For example, a bird won't fly past time and time again until you have the cameras white balance set correctly for that specific scene.
- What I need to emphasize is the time required for post processing. Alot of you photographers say it doesn't take that long. LIAR!!! It only doesn't take long if you know what you're doing! OMG I'm still trying to figure out how to get the proper colors in photoshop, what a "layer" is, or heck... what exposure should I set it to for the best look. My eye is not a trained eye. my definition of "ok" is not so "ok" to experienced people.
* Personally what I've just learned (decided on) is instead of taking Full size JPG's which I currently do. I am going to take RAW and just batch convert them to TIFF. I was reading how JPG is best compression for email and such but I want quality. Editing the JPG I have the suspicion that I am losing too much. I want as close to lossless data as I can get.


11. The best way to learn what your SLR camera can do, is through experimentation. If your taking a photograph of running water, try both fast and slow shutter speeds to see for yourself what the difference is. Or if your photographing a beautiful landscape, try different aperture settings. You'll be surprised at how many photo's you can get from shooting the same scenery with different settings.
- Practice makes perfect, yah yah yah

12. Always press the shutter button half way down to prefocus before going all the way and taking the photograph. This will usually result in clearer photo's every time. It is also especially useful when you can anticipate where a subject is going to be positioned before it gets there. You can prefocus on that spot by pressing and holding the shutter button half way, then as it comes into view, press the rest of the way down.
- OK, I knew this but I think I will use Center weight (I think it's called?) focus. the IQ of these DSLR's aren't perfect. Auto helps by giving you an idea. You gotta pick the settings for the scene and what you want out of it.

I was looking for advice sites like stobist and found this one for dummies like me.

Digital SLR photography tips for beginners amateurs

I am only gonna list the first 5 tips but this site looks like it was made for 1st time DSLR owners. It answered a bunch of things I already found out and questions I still had.

# Don't throw your camera manual away. It will become your new best friend. Read it as often as possible, especially in the first couple of months after purchasing your DSLR camera. Always store it somewhere handy. For example in your camera bag.

# Buy a UV filter for each lens you own. It's easier to replace a scratched lens filter than it is to replace your actual lens.

Thanks everyone for so many options!

I will try to visit BHPhoto this weekend to test out a Sigma 10-20 and the Pentax DA 14mm again. The 14mm looked distorted to me when I looked at my hand through the viewfinder. I want to try to shoot a portrait body shot from 2-3 feet.

Hi everyone. a new K20d owner here.

My 18-55 kit lens isn't wide enough for me but I went to the store and looked at the Pentax 14mm prime and the fisheye distortion was too much for me.

Cant you tell me what you think is the widest lens available for Pentax with the least or no distortion?

thanks.

K20D impression from a new DSLR owner
Posted By kiamon

Hi all,

Here are my impressions of the K20D as a totally new DLSR owner

I own TONS of compact cameras and finally decided on a DSLR. The new Canon Rebel Xsi or 40D seemed the best choices due to the reviews but although the IQ and lens selection are great... as well I decided the Pentax 20D was a better fit for me for the weather sealing and prime pancake lenses.

Take pictures at first was weird and having to read the manual and read alot of forums.

*the following is just what I see as a new owner. feel free to give me advice*

Lesson 1 - Learn to use manual settings and tricks
The pictures are underexposed. Not everything I want is in focus. After reading the forums I stopped using the default automatic User settings. I set my exposure to .5 EV higher. that helped a bit but I learned my first big lesson. I can't use a DSLR on auto user settings. I tried a cool trick in a picture I just ZOOM in on what I want to be clear then half-press the shutter to focus then I zoom out
again and take the picture. Definitely learn to do things yourself and don't just press the shutter expecting the camera to take a good picture.

Lesson 2 - Live view sucks balls and the in camera flash too.
OK the Live view is dirt slow and feels weird since the image in the LCD syncs slowly as well. After using the in camera flash I learned that NONE of those nice pictures I see in the internet and magazines use the in camera flash. I saw an article on using a styrofoam bowl around the lens as a diffuser for the in camera flash. I will try that later.

Lesson 3 - Lighting is ALOT and also get a good flash
When on top of Taipei 101 (tallest building the world) I thought the sunlight was all I needed for crystal pictures. Nope. The sky was nice but my friend was underexposed. Learned to keep the Sun to your back. if you shoot with the sun behind your subject then your subject will be DARK. Unless you have a good flash I think. I have been using the K20D to shoot my own impromptu home porn as well and the constant movement definite requires the flash. Also a wider lens. I have the 18-55 kit lens and even at 18mm I wish it were just a wee bit wider for full body shot at close range. I went to BHphoto to look at the 14mm prime but it was too "fisheye" for me. maybe the 21mm prime will work. I have to look into it.

I am also going to look for some "full-spectrum" light bulbs. I hear these home light bulbs produce near full spectrum like daylight. I am wondering if it will make a difference in my apartment. Anyone have any experience with these?

Lesson 4 - Lens Hood or lens cap
I am unsure about these. the lens hood is to prevent sunglare. Do I need it in a bright indoor setting? The lens cap is to protect the lens so I always keep it on. Its a pain though when I am outside and the lens hood is on my camera with makes it a pain to take the cap on and off all the time. I am also worried that my lens cap might hit the lens while I am putting it on due to clumsy fingers. Will it scratch my lens?

Lesson 5 - In Progress The aperture shutter speeds. I dont know how to change the shutter speeds so i only fiddle with the F-stop number. I wish the kit lens would go lower than 4.0. I want a sharp clear image which I haven't been getting. Advice on this board is to get a good flash before investing in tons of lenses so I am sticking with the 18-55 f4 kit lens until I learn the camera but I just purchased the Metz 58 AF1 (OUCH! $$$). and the LowePro Rezo 160 AW shoulder bag which fits the camera and flash perfectly while staying compact. It should also let me carry 1-2 prime lenses as well when I get to that point later. I have alot of work to catch up with now but on the weekends I will start trying to see what I can do (learn) with my new K20D.

Hi all.

I just got my first DSLR Pentax K20d last week while I was in Taiwan. I usually buy a new point and shoot compact every 6 months and my photos always sucked compared to other tourists I see so I decided to take the plunge.

The last straw was Viet-Nam in the Cu Chi tunnels where I couldn't take any pics in the tunnels without my flash overexposing or me getting nothing and I ended up borrowing my korean friends' Canon Rebel something to take pics. His flash would go off twice and I'd get a clear picture in the tunnel. Never saw the 2 flash thing before but after reading this forum and a few other sites, now I know (mostly I think).

Well I figured that I wouldn't buy another new camera for 4 years after this baby but... there are I$$UE$... The issue is that I need more len$e$ and acce$$orie$!

Now I find the in camera flash isn't so great so I was going to get the Pentax AF540fgz but THANKS TO THIS BOARD I am going straight for the Metz 58. I am so glad no store gave me a good price on the af540fgz in Taiwan or else I'd have been stuck with a problem child flash.

I am going to post soon for advice on the lens and any other equipment I need in the other forum. My needs are quite varied and a little "unorthodox" so please be kind.
